VAPOR-BURNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 624,823, dated May 9, 1899. Application filed December 2, 1898. Serial No. 698,111. (No model.)

To ctZl whom it may concern: V

Be it known that I, ARTHUR KITSON, a subject of the Queen of Great Britain, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Vapor-Burning Apparatus, of which the following is a specification.

My invention relates to vapor-burning ap paratus, and is more specifically designed to produce an improvedform of burner to be used in conjunction with the well-known WVelsbach or other incandescent mantle and to vaporize the hydrocarbon-supply by the heat of the burner itself.

The preferred form of construction is illustrated in the accompanying two sheets of drawings, in which Figure 1 is a side view and partial central vertical section of the apparatus with a portion of the standard broken away. Fig. 2 is a similar view taken at right angles to the plane of Fig. 1, and Fig. 3 is a plan view with the gauze, burner, and mantle removed.

Throughout the drawings like referencefigures refer to like parts.

1 represents the base, having a cored-out screw-threaded recess by which it may be" mounted on a threaded support. 2 2 represent the uprights from said base, riveted or screwed thereto and supporting the annular casting 8 and the annular thimble-plate 4, the same being held together by rivets or screws 5 5. The casting 3 has a downwardly-extending cone-shaped central portion 3,which was several openings 6 and terminates in the threaded apex 7. Into this threaded apex is screwed the valve or vapor chamber 8, in the shape of a screw-pl u g, which has an upwardlyopening discharge controlled by the needlevalve 9, mounted in said vapor-chamber or valve-chamber S by a screw-threading, renderin g the valve adjustable in the well-known way, and 10 is a vapor-tube supplying vapor to said vapor or hydrocarbon chamber 8, and this tube has a spirally-coiled portion 10:.

The annular plate 4 has a thimble 11 extending up from the internal edges thereof, and on that is mounted the thimble 12, which forms the main portion of the cylindrical V317 por-burner. III the upper portion of this cylinder 12 is mounted a gauzediaphragm of wire 13. Over this is placed the perforated cap 14, of gauze or sheet metal, which has openings at the top and upper sides, as shown. This cap 14 has a ring of perforations 14 through the sides near the upper end or perforated diaphragm which forms the top of the burner.

15 is a rotating conical piece mounted on v and rotating on the conical portion 3 of the casting 3 and having openings corresponding to those marked 6.

g 16 is a lug projecting from the side of the main burner-thimble 12, provided with a setscrew 17 arranged to grasp an outwardly-extending wire 18, which supports the incandescent mantle 19 over the burner.

The jets of flame issuing through the ring of perforations 14 serve to heat the lower end of the mantle andlraise it to incandescence and also to heat the coil of the vaporizingtube, which surrounds the lower portion of said mantle and is opposite and encircles the perforated portion of the burner, the mantle coming between the coil of the vaporizingtube and the burner, as shown.

The mode of operation of my invention is as follows: The burner being in operation, the jet of vapor controlled by the needle-valve 9 passes up the cylindrical burner, drawing in the necessary amount of air through the openings 6, which may be graduated by turning the skeleton thimble 15 so as to coversaid openings more or less. The upward current of vapor and air form a combustible mixture, which passes through the gauze diaphragm 13 and burns both inside and outside of the perforated cap 14. The fluid hydrocarbon, which may be gasoline or similar substance, is supplied under pressure and is vaporized in the coil portion 1O of the vaporizing-tube and reaches the hydrocarbon-chamber Sin vapor form, ready to be discharged through the needle-valve. The flame of the burner heats the incandescent mantle19 to an intense degree and causes the same to give off a strong light. Thus the burner is self-supporting in its action. 7

The interposition of the lower po rtion of the i mantle between the side perforations in the perforated burner-cap 14 and the vaporizingcoil of tube 10 serves a useful purpose in limiting and concentrating said side jets in the immediate vicinity of the vaporizing-tube. Otherwise the side jets might Straggle out in a manner that would be unsightly and dangerous and also disseminate their heat. By interposing the skirt of the mantle all flamejets are concentrated within its circumference or only allowed to filter through it slightly, and the heat given up to the mantle is radiated by it in a constant and powerful volume upon the surrounding vaporizing-tube. At the same time no ragged jets of flame are visible. The advantages of this arrangement over one in which a metal gauze is used are that the metal gauze will burn out if the flame is within it, while the mantle will not burn out, at least not until the whole mantle requires renewing. If the holes in the side of the cap are madeso small that the flame will be kept outside of them, which is an equivalent construction to the use of fine wire-gauze, the inclosing concentrating action of the surroundingmantle is still more desirable to prevent spreading of the flame and dissemination of the heat.

I do not herein claim, broadly, the combination of avapor-burner having at its upper end a ring of perforations and gauze covering said perforations and a coiled vaporizing-tube encircling-said gauze-covered perforations, as the same is described and claimed in 1n y pending application, Serial No. 095,932, filed November 9, 1898.

Having therefore described my invention,

- what I claim as new, and desire to protect by Letters Patent, is-

1. In a vapor-burning apparatus the combination of the vapor-burner having at its upperend a ring of perforations, a coiled vaporizing-tube encircling the perforated portion of said burner, and the incandescent mantle for said burner having its lower portion surrounding the burner and within the coil of the vaporizing-tube, substantially as described. I

2. In a vapor-burning apparatus the combination of the vapor-burner having a perforated diaphragm in its upper end, and a ring of perforations through the sides of the burner near said upper end, a coiled vaporizing-tube encircling the perforated portion of said burner, and the incandescent mantle for said burner having its lower portion surrounding the burner and within the coil of the vaporizing-tube, substantially as described.

Signed by me, at New York, this 26th day of November, 1898.

ARTHUR KITSON.
